Glow Plug Timer

Glow Plug Timer

The glow plug timer receives a constant battery feed from the 100A fuse located in the fuse holder (C1875) on an R wire, and a second feed from the energised ECM relay (C1895) via fuse 2 of the engine compartment fuse box (C0570) on an R then RW wire.

When all starting parameters have been met, the ECM (C0606) provides a control feed to the glow plug timer (C0190) on a BR wire. The glow plug timer (C0190) will now power the glow plugs as follows:

Glow plug number 1 (C0476) on a BG wire. Glow plug number 2 (C0477) on a BP wire. Glow plug number 3 (C0478) on a BY wire. Glow plug number 4 (C0479) on a BR wire. Glow plug number 5 (C1500) on a BW wire. Glow plug number 6 (C1501) on a BN wire.

All six glow plugs are earthed via their fixings. The glow plug timer (C0190) is earthed on an NO wire.

The ECM (C0606) monitors the fault status of the glow plug timer (C0190) via a BY wire.

Starter Motor

The battery (C1641) provides a constant battery feed to the starter motor solenoid (C0178) on an R wire. Operation of the starter solenoid is controlled by the immobilisation ECU. When the immobilisation ECU (C0059) receives an ignition crank feed from the ignition switch (and all other starting parameters have been met) it provides a feed to the starter motor solenoid (C0179) on a B then BY wire. The energised starter solenoid allows the battery feed to power the starter motor.

The starter motor (C0823) also provides an 'engine start' signal back to the ECM (C0606) on a BG wire.

Fuel Pump

When the engine is started, the ECM (C0331) provides an earth path for the fuel pump relay coil (C2022) on a BP wire. The energised fuel pump relay (C2022) provides a feed to the fuel pump (C0114) on a WU wire. The fuel pump (C0114) is earthed on an N wire.
